WALTER J. BARRON, YORK, N. Y., ASSIGNOR TO REMINGTON TYPEWRITER COMPANY,OF ILION, NEW YORK, A CORPORATION OF NEW YORK."

mmwm'rme MACHINE.

To all wii om it may concern;

Be'it known that I, WALTER J. BARRON,

citizen of .the United .States, and resident of the borough of Brooklyn,city of New enabling predetermined widthwise portions York, in thecounty of Kings and State-of New York, have invented certain new anduseful Improvements in Type-Vriting Machines, of which the following isa specifithe character specified.

More specifically one object of the invention is to provide improvedmeansfor en abling the ribbon to be used throughout substantially itsentire width in that class of machines wherein the ribbon is vibrated atthe printing operation and more especially in machines which 'employ ashiftable platenp Another object is to provide means for of the ribbonto be employed at will in ma,-

chines of the character referred to thus providing for the use of atwo-colorrlbbon- -or one having a plurality of-w1dthw1se fieldsdiffering in character.

consists in the features of construction, 'combinatio'ns of devices andarrangements of parts hereinafter described and particularly pointed outin the claims.

. In the present embodiment of my' invention I- provide a vibrator whichis formed with a slot, theiupper edge of which is stepped, thus enablingthe vibrator to be taken up at different po1nts by the oper ating leverinthecourse of its movement. Said operating lever is pivoted to vibratetoward and from the printing point and .is

' also pivoted to swing widthwise of the direction of its, vibratorymovement,. the swinging movement being controlled by hand operated meansand enabling theopcrating lever togbe normally positioned opposite oneor another of the steps on the vibrator.

Both the vibrator and the opcrating lever which engages with it aresupported on fixed parts of the machine buttheir actuating or vibratingdevices are shifted automatically, when the platen'is shifted to changecase, by novel devices which are operated by the platen shifting frame.

To the above and other ends my invention Specification ofLetters-Patent. Patented Feb. 20, 1912. Application filed Ianuary 26,191 1. ,Serial No. 604,780.

Fig. 6- is front view in vertical section of themounting of the operating lever. Fig. 7 is a face view of part of 'aribbon, showing the courses orpaths followed by the types. I

As appears from Figs. 1 and.2, the main frame of the machine comprises"abase 1, posts'2 and a top plate 3; Abovethetop plate are fixedtrackways t cooperating through. anti friction rolls. 5 with a. truck 6connected by links -7' to a platen frame- 8, which carries a'rotaryplaten 9. A roller 10 mounted on the platen frame runs on a shift rail11 mounted on uprights 12 con- .nected by a cross rod or bar 13 from theends of which depend arms 14 pivotally connected at-theirlower endswiths iftkey levers 15, which whensoperated, raise the shift frame and shiftthe platen frame and platen on the truck 6 to change case: The truck andplaten frame togetherconstitute'a carriage which is urged leftward by aspring drum (not shown), the leftward step-by- "s ep movements of thecarriage being controlled by feeding..dev iiws-avhich comprise a rack 16on the carriage and meshes with a pinion 17 operatively connected with atoothed escapement wheel 18 with which cooperatefeed dogs 19 and 20mounted at the top of a pivoted dog rocker $21. The dog rocker isconnected by a link 22 with an arm 23 fixed to a rock shaft 24:, saidrock shaft having crankarnis .25 connected by links 26 to a universalbar27 underlying a set of key levers 28. -Each key lever is connected by alink 29, le'ver'30 and second link 31 with a type bar 32 pivoted on ahanger 33 secured at the front of a stafiimary segment "'34. "The typebars are Eirmlarly' arranged and are adapted to 006perate with the frontface of the platen.

-. 'Ribbon'spools 85, (shown in Figs. 1 and 2) are vertically disposed,one at each side of-the machine, forward of. the platen and belowthe topplate. Each ribbon spool is supported on a horizontal shaft 36 whichcarries at its rear end a bev'eledgear 37 adapted to mesh with a beveledgear 38 on a driving shaft 39, which is connected with the spring. drumin a lmown manner so as to receive'movements therefrom, and is shiftabieendwise so as to connect in alternation with the ribbon spools and feedthe ribbon longitudinally back and forth.

The parts heretofore described are comv.mon to the No. 10 Remingtonmachine with which I have preferred to show my invention as associated,although it is to be understoodthat various features of invention may beemployed in connection wit-h other forms of writing machines.

The ribbon 40, which in the present case is divided into longitudinalfields a and b of different characteristics or colors, is

' or vibrator which comprises upright paralguided from the spools overguides 41 and directed inward and rearward toward theprinting face ofthe platen, being threaded through slots in a vibratory ribbon carrierlel arms 42 connected at their lower ends by' a plate-like body portion-43 which is olfset rearward, as indicated at 43, and ex tends downwardbehind the type bar segment 34, providing a stem 43". The stem v43 hastwovertical guide slots 44 which cooperate with lieaded'guide screws 45secured in the rear face of the segment 34.

A coiled spring 46 connects the elf-set portion 43 with the segment 34and tends constantly to pullthe vibrator downward, normallymaintaining'the 0111p 1' ends of the slots 44 in contact with th:guiding screws 45, thus retaining the printing portion of the ribbonbelow the point. I Just below the off-set 43 thefstem 43 is formed withthe slot 47, the lower edge of which is horizontal, the upper edge beingcut to provide'a plurality of engaging devices or steps numberedrespectively 48, 49,

50, 51 and 52. The slot 47 receives the forward end portion of anoperating lever 53 fulcrumed at 54 on a rotary member, device or sleeve55 which bears on a headed shouldered screw 56 that screws up into a lug3 on the top plate 3. The mounting of the operating lever is best shownin Fig. 6. It will-'be understood that .said operating lever may swingup or down in a vertical plane about the pivotal center 55 and may alsoswing laterally or transversely of the vertical plane about the axis ofthe screw or fixed bearing 56 as a center. The rear arm ofthe operatinglever is constantly ment with the upper edge 59.

urged upward by a coiled spring 57 which is anchored to a pin 58 on thetop plate and normally maintains the forward end portion of theoperating lever in contact with the bottom horizontal edge of the slot47. The

upper edge 59 of the rear arm of the oper atinglever is slightly curvedand said rear arm terminates in an upright finger or The actuatinglinkis adapted to be moved.

forward and backward toward and away from the fulcrum 54 of theoperating lever by devices which operate automatically when theplaten-is shifted so as to increase the throw of the vibrator when theplaten is in upper case position and lessen the throw when the platen isrestored to lower caseposition. Said devices comprise aswin ing lever 63shown detached in Fig." 4.

3, is pivoted at 64 to the sleeve 55 below the fulcrum 'of the operatinglever. The lower end of the swinging lever is provided with 'a rearwardvoifset 65 formed with a slot 66 through which the actuating'link 62passes.

aid swinging lever, as appears from Figs. 1 and- The upper arm ofitheswinging lgver is provided with a forwardly curved nose '67. Adapted tocooperate with said nose is a cam edge 68 which forms the rearwardtermination of an arm 69 fast on the shift rod 13. In lowercasepositionthe cam 68 coiiperates with the nose 67 to maintain the swinging lever,as in Fig. 1, thus locating the link 62 in its rearmcst position, theroller '61 being farthest from the fulcrum 54 so that the least extentof movement will be communicated to the operating leverat.

printing operation. -When, however, the platen is shifted upward-as inFig.3, the cam 68 cams the nose 67 rearward, swinging the lower arm ofthe lever 63 forward and correspondingly swinging the'link 62 so thatthe roller 61 will operate nearer the fulcrum 64 and communicate agreater extent 1 of throw to the operating lever so as .to compensatefor the-increased throw necessary to elevate the ribbon to cover theprint-- ing point on the shifted platen. As stated, the edge 59 has, aslight curvature.

center of the curve is co axial with the cen-- ter about whicl-Qthelinkhfi2 swings so that the forward/,and backwa d. movements oi theroller 61 alo'ngits traclf 59 will not affect the operating'lever.

It will be understood that at printing op- The ,erations the printingkeys actthroughthe the same and present the ribbon to the print ingpoint on the platen. The point at which the vibrator will be picked upwill depend on the step on the vibrator which the operating leverunderlies. For example, when the operating lever underlies the step 48,it

. will be closely ponnected with the vibrator and the latter will startto lnove when the operat ngdever starts; while if the operating leverunderlies the step 51 the operating level will move a considerabledistance before it acts on the vibrator. Thus it will be seen that bylocating the operating lever under one or another of the steps theextent of throw communicated to the vibrator and the ribbon will bevaried at will. In order to so locate the operating lever I providedevices which cooperatewith said lever to' swing it transversely of thevibrator on the bearing screw 56. Said devices, as best appears fromFigs. 2 and 5, comprise a slide bar 70 which terminates at its inner endin an upright portion 71 formed with an open vertical slot- 72 whichreceives and controls the forward end portion of the operating lever 53.The left-hand portion of the slide bar 70 is guided on a fixed bracket73 and the right-hand-end of said slide bar is piv- Y otally connectedat 74 with an upright crank will be observed that the pointer-has thedouble functions of an'indicator and a stop device. The upper edge ofthe slide bar.

arm 75 which is pivoted at the rear end of a 'rock shaft 76, the latterbearing in a fixed lug T7 and extending forward and through theright-hand front corner post 2, terminating in a-knurled finger buttonor key 78-.

Forward of the corner post the rock shaft 76 is provided with an uprightpointer 79 which cooperates with indicating marks 80, 81 and 82 formedon an indicating plate 83 secured to the corner post. A-swinging stop84is adapted to co-act with the pointer to limit the leftward turningmovements of the rock shaft and connected parts but said stop may beswung upward and out of operation so as to permitsaid pointer to co-actwith a fixed stop orforwardly extending stud 85, the stud 85 permittingfurther left-. ward movement of the pointer and rock shaft than does themovable stop 8%. It

70 is provided with a series offnotches 8G whiclnare engageable by thefree end of a spring detentST secured at 8S,to the frame of the machine.By turning the key-or button 78 the rock shaft may be rocked to and fro,sliding the bar 70 in and out and swinging the operating lever laterallyso as to lovibrator and ribbon.

cate'it beneath one or another'of the steps on the vibrator. There arefour operating steps on the vibrator and an additional step 52 which isso located that itwillnever be reached by the operating lever during-itsswing and so will provide for allowing the vibrator to remain quiescentduring printing operations when it is desired to operate the typewriterfor stencil or mimeograph work. The cooperating detent devices 87 and 86will maintain the' slide bar and connected parts in set or predeterminedpositions so that the slotted guide 71 maybe set at will to confine theoperating lever between the walls of the guide slot 72 to predeterminedpaths of. up and down vibration. As stated, there are four steps on thevibrator with which the operating lever co-acts to lift the VV'hen thelever coacts with the step 51 the lost motion will-be greatest and thevibrator will be elevated to its least extent so that the types willfollow a path w (Fig. 7) along the upper portion of the ribbon field a.lVhen, as shown in Fig. 2, the operating-leveris located be neath thestep 50 the vibrator and ribbon will be elevated to a slightly greaterextent and so as to cause the-types toprint along the lower portion ofthe printlngfield win the path represented by the dotted line in Fig. 7.correspondingly, when the operating lever is locatedoppositethe steps 49and 48 the vibrator and ribbon will be elevated so as to presentrespectively the upper and lower portions of the printing field b to thetypes and cause said types to follow the paths indicated by the dottedlines 1 and 2 in Fig. 7. Thus it will be seen that I- provide for makinguse of the ribbon in four parallel paths,- thus thoroilghly exhaustingthe printing surface.

Each of the color indicating marks corresponds to two set positions ofthe operating lever. hen the operatinglever is operated under the step51 the pointer 79 will be in contact with the stop 84'so that ordinarilyitwill not be possible to throw the operating lever out of operativerelationship with the vibrator. lVhen it is desired to render theoperating lever i'noperative,-as for niimeographing purposes or thelike, thestop Si is thrown out and the'finger' key 78 turned to bringthe pointer or stop 79 into engagement with the stop 85, thus moving theconnected parts so as to reset the ope 'i ating lever under the step 52.In the opposite" direction or toward the right the movements of the handoperated parts are limited'by a stop 89 with which the pointer 79isfadaptedfto conta'c'tj.-

It will be observed. that by my "present invention I provide a vibratoi'which has a single normal position but which is adapted to be vibratedor thrown a 'pliirality of different extents for both the lower andupper case positions of the shiftable platen by improved devices whichcomprise an op erating lever having a double movement, one a vibratorymovement and the other movement transverse of the vibratory movement,the transverse movement changing the normal relationship between theoperating lever and the vibrator so that the throw of the lever may bevaried The operating lever is shittable to vary the throw of thevibrator and the actuating link is shittable to vary the throw of theoperating lever. In other words, there is an element t 6., the operatinglever, which is shittal'ile to vary the ribbon throw and which in turnis actuated by devices which are themselvesshiftable to vary the throw.My invention pro vides improved and simplified means for obtaining acomparatively large number, four in the present case, of paths of use\vidthwise of the ribbon so to thoroughly exhaust the ink therefrom.
